Data compression is the compacting of data by lowering the number of bits which are stored or transmitted. Thus, the compressed info takes less disk space than the original one, so a lot more content might be stored on identical amount of space. You can find many different compression algorithms which function in different ways and with a lot of them only the redundant bits are deleted, which means that once the information is uncompressed, there's no loss of quality. Others erase unnecessary bits, but uncompressing the data later on will result in lower quality compared to the original. Compressing and uncompressing content requires a significant amount of system resources, especially CPU processing time, so every web hosting platform which uses compression in real time must have ample power to support this attribute. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of saving the actual code.
Data Compression in Website Hosting
The compression algorithm employed by the ZFS file system that runs on our cloud internet hosting platform is called LZ4. It can supercharge the performance of any website hosted in a website hosting account with us since not only does it compress info more effectively than algorithms used by other file systems, but it uncompresses data at speeds that are higher than the hard disk reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform because it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to create backups at a higher speed and on less disk space, so we shall have several daily backups of your files and databases and their generation won't change the performance of the servers. That way, we could always restore any kind of content that you may have removed by mistake.
